In a method implemented in a communication device an available bandwidth for transmitting one or more data frames is determined, wherein the available bandwidth corresponds to a first composite communication channel comprising a plurality of communication channels. A plurality of semiconductor transistors having an array structure are arranged in each of the analytic regions. The base station carries out assignment of radio resources using the report information. A count of how many of the non-volatile storage elements in the group showed a different result between the reads for the two most recent read levels is determined.
